Terms Meaning
O
Operating pressure
range
Pressure range in which product is operable.
Operating temp. range Ambient temperature range in which product is operable.
P
Part in contact with
fluid (wetted part)
A part that comes into physical contact with the fluid.
Power saving mode
The condition in which the digital display turns off and the current consumption is
reduced.
Pressure
characteristics Indicates the change in the display value and analogue output when fluid pressure
changes.
Proof pressure Burst pressure at which the product is electrically or mechanically damaged.
R Rated flow range The flow range within which the product will meet all published specifications.
Rated pressure range The pressure range that satisfies the specifications.
Repeatability
Reproducibility of the display or analogue output value, when the measured quantity is
repeatedly increased and decreased.
Response time Time from when the target flow is applied until the flow reaches 90% of the set value.
S
Set flow range
The range of ON/OFF threshold values that can be set for those products with a switch
output.
Switch output
Output type that has only 2 conditions, ON or OFF. When in the ON condition an
indicator light will show, and any connected load will be powered. When in the OFF
condition, there will be no indicator light and no power supplied to the load.
T
Temperature
characteristics Indicates the change in the display value and analogue output caused by ambient
temperature changes.
U
Unit selection function
A function to select display units other than the international unit (SI unit) specified in
the new Japanese measurement law. Flow can only be displayed by SI units in Japan.
Union Fitting which is connected to the vinyl chloride piping (tube piping).
W
Water hammer
A momentary steep pressure increase due the spread of pressure by closing a
contactor such as a valve for an extremely short time while there is a flow.
This pressure increase is known as water hammer or impact pressure.
Window comparator
mode An operating mode in which the switch output is turned on and off depending on
whether the flow is inside or outside the range of two set values.
